vrx5 will give you surge at cruise and be harder in parkinglots. the surge would go away maybe with 373s but thats more on the bill.
we have a custom cam right now out wiping up the streets in Mexico that is pretty easy to drive and requires no gears later. it runs $370. It is better designed than the vrx4 but easier to drive than the x5.

our morels (same as everyone elses) run $15 cheaper than anyone's and our ls7 lifters well. Wanna stay on or below budget, talk to us! Pm or email me.
